LONDON — One very familiar face will be missing from the Stella McCartney fall 2019 show in Paris on Monday, that of Stephane Jaspar, who has left his role as chief marketing officer of the brand.

“We all wish Stephane a bright and brilliant future, and feel so grateful for all he contributed over the years. We wish him much love and success,” said McCartney.

The Manhattan-based Frenchman joined Stella McCartney in 2003, two years after the designer launched her eponymous fashion house as a 50-50 partnership with the group now known as Kering.

Over the years, Jaspar worked closely with McCartney and with the chief executives who ran her business, including Marco Bizzarri, who is now leading Gucci, and Frederick Lukoff, the current president and ceo.

With his sharp wit and business sense, Jaspar promoted the brand through years of growth and expansion, including the launch of myriad product categories, fragrances, men’s wear, a deal with Adidas and store openings across the globe.

He was by McCartney’s side on the sustainability front, too, helping to support the designer’s eco-friendly, leather- and fur-free sourcing and supply-chain strategies and the creation of an environmental profit-and-loss account.

He also worked closely with McCartney as she announced her decision to part ways with Kering last year. As reported, McCartney is in the midst of a two-year transition that will see her company become fully independent by 2020.

Before joining Stella McCartney, Jaspar worked at Miramax films for six years, and later at Nadine Johnson in New York. It is understood he will take up another role, based in New York. His replacement at Stella McCartney has yet to be announced.
